技术领域technical field
本发明涉及移动通信系统。具体地说，本发明涉及具有多个收发器的移动装置对网络接入点的智能选择。The present invention relates to mobile communication systems. In particular, the present invention relates to intelligent selection of network access points by mobile devices having multiple transceivers.
背景技术Background technique
诸如蜂窝电话、PDA一类的移动装置前所未有地增多着。几乎每个人都有某种移动装置，有的人还有多个装置。用户可以使用单个移动装置访问几个不同的网络，并可从诸如服务器、其它移动装置等其它网络实体获取语音、文本及多媒体数据。此外，随着越来越多先进且节能的处理器、显示接口及应用的出现，移动装置的复杂度越来越高，为用户提供了前所未有的体验。这样的装置包括例如iPhone、iPad、Driod及其它PDA/上网本。这样一来，用户更加频繁地使用他们的移动装置，并对数据、电子邮件、语音等有更大的带宽需求。Mobile devices such as cellular phones, PDAs, and the like are proliferating like never before. Almost everyone has some kind of mobile device, and some have more than one. A user can use a single mobile device to access several different networks and obtain voice, text and multimedia data from other network entities such as servers, other mobile devices, and so on. In addition, with the emergence of more and more advanced and energy-efficient processors, display interfaces and applications, the complexity of mobile devices is increasing, providing users with an unprecedented experience. Such devices include, for example, iPhones, iPads, Driods, and other PDAs/netbooks. As a result, users are using their mobile devices more frequently and have greater bandwidth demands for data, email, voice, and more.
这种使用量的增加给提供这些服务的网络造成巨大的压力。即使出现了使用因特网协议（IP）寻址、会话发起协议（SIP）等的3G和4G网络，还是有一些网元过载，造成数据流的瓶颈，例如蜂窝基站（或者称为节点B）及其相关联的网关。在一个或多个基站范围内正在从网络下载大量数据的几个用户将向基站提出更大的传输功率需求。这可能导致每个移动装置的信号强度下降，结果导致更低质量的连接。传输功率控制可以减轻一些问题，但不能解决全部。这还造成移动装置自身更高的电池耗用。This increase in usage puts enormous strain on the networks that provide these services. Even with the emergence of 3G and 4G networks using Internet Protocol (IP) addressing, Session Initiation Protocol (SIP), etc., there are still some network elements that are overloaded and create data flow bottlenecks, such as cellular base stations (or Node Bs) and their associated gateway. Several users who are downloading large amounts of data from the network within range of one or more base stations will place greater transmission power demands on the base stations. This can lead to a drop in signal strength for each mobile device, resulting in a lower quality connection. Transmit power control can alleviate some problems, but not all of them. This also results in higher battery drain on the mobile device itself.
网络运营商通常提供连接到他们的核心网、或者连接到因特网的替代方式。飞蜂窝（femtocell）、光纤到节点（FTTN）和无线局域网（WLAN或Wi-Fi）接入点可以为具有多种类型收发器的移动装置提供到不同网络的接入。例如，iPhone包括Wi-Fi收发器。Wi-Fi热点/接入点可被用来以宽带速度连接到网络，因而可以减轻蜂窝网络的负荷。然而，还有一些特定的问题妨碍对接入点的有效率的选择。例如，很多用户也许出于以下原因而禁用Wi-Fi：(a)对电池寿命的担心；或者(b)为了避免每次检测到开放的接入点就收到连接到Wi-Fi的扰人消息。结果，用户经常不启用Wi-Fi，因为他们可能事后忘记关闭。一直打开Wi-Fi会导致电池消耗得更快，一直关闭Wi-Fi则会导致连接问题以及次优的电能使用，因为蜂窝收发器可能不得不使用更多的电力与基站之间进行高吞吐率的通信。用户与连接管理器之间为启用/禁用Wi-Fi收发器不断进行交互，这无法实现无缝的、流畅的用户体验。Network operators often offer alternative ways of connecting to their core networks, or to the Internet. Femtocell, fiber-to-the-node (FTTN), and wireless local area network (WLAN or Wi-Fi) access points can provide mobile devices with multiple types of transceivers access to different networks. For example, the iPhone includes a Wi-Fi transceiver. Wi-Fi hotspots/access points can be used to connect to the Internet at broadband speeds, thus offloading the cellular network. However, there are certain issues that prevent efficient selection of access points. For example, many users may disable Wi-Fi due to: (a) concerns about battery life; or (b) to avoid being disturbed by connecting to Wi-Fi every time an open access point is detected information. As a result, users often don't enable Wi-Fi because they may forget to turn it off afterward. Having Wi-Fi turned on all the time will drain the battery faster, and turning Wi-Fi off all the time will cause connectivity issues and sub-optimal power usage, since the cellular transceiver may have to use more power to communicate with the base station at a high throughput rate Communication. The constant interaction between the user and the connection manager to enable/disable the Wi-Fi transceiver does not allow for a seamless and smooth user experience.
因此，所需的是在任何给定的时间及地点，智能地判断移动装置是否可能处于接入点的附近，以及基于环境判断其是否为最优连接类型的技术手段。What is needed, therefore, is a means of intelligently determining whether a mobile device is likely to be in the vicinity of an access point at any given time and location, and whether it is the optimal type of connection based on the circumstances.

这里及全文中使用的“移动装置”一词是指能够无线地发送及接收数据的任何电子装置。移动装置可具有处理器、存储器、收发器、输入和输出。这样的装置的例子包括蜂窝电话、个人数字助手（PDA）、便携计算机等。存储器存储应用、软件或逻辑。处理器的例子是计算机处理器（处理单元）、微处理器、数字信号处理器、控制器及微控制器等。可包括逻辑的装置存储器的例子包括RAM（随机访问存储器）、闪存、ROM（只读存储器）、EPROM（可擦写可编程只读存储器）及EEPROM（电可擦写可编程只读存储器）。The term "mobile device" as used herein and throughout refers to any electronic device capable of sending and receiving data wirelessly. A mobile device may have a processor, memory, transceiver, input and output. Examples of such devices include cellular telephones, personal digital assistants (PDAs), portable computers, and the like. The memory stores applications, software or logic. Examples of processors are computer processors (processing units), microprocessors, digital signal processors, controllers, microcontrollers, and the like. Examples of device memory that may include logic include RAM (Random Access Memory), Flash memory, ROM (Read Only Memory), EPROM (Erasable Programmable Read Only Memory), and EEPROM (Electrically Erasable Programmable Read Only Memory).
这里及全文中使用的“逻辑”一词是指具有可用来指挥处理器运行的指令信号和/或数据的形式的任何信息。逻辑可由存储在装置存储器中的信号构成。软件是这种逻辑的一个例子。逻辑也可以由数字和/或模拟硬件电路构成，例如包括逻辑AND、OR、XOR、NAND、NOR及其他逻辑运算的硬件电路。逻辑可由软件和硬件的组合构成。在网络中，逻辑可被编程在一个服务器或一组服务器中。具体的逻辑单元不限于网络上的单个逻辑位置。The term "logic" as used herein and throughout refers to any information in the form of instruction signals and/or data that can be used to direct a processor to operate. Logic may consist of signals stored in device memory. Software is an example of this logic. Logic may also consist of digital and/or analog hardware circuits, such as hardware circuits including logical AND, OR, XOR, NAND, NOR, and other logical operations. Logic may consist of a combination of software and hardware. In a network, logic can be programmed in a server or a group of servers. A specific logical unit is not limited to a single logical location on the network.
移动装置经由网络彼此之间或与其它元件之间通信，网络例如为无线网络或有线网络。“网络”可包括诸如蜂窝网络的宽带广域网、局域网（LAN）、无线LAN（Wi-Fi）及个人局部网络，例如包括蓝牙（RTM）在内的近场通信（NFC）网络。网络上的通信优选地是基于分组的；然而，无线电调频/调幅网络可使用适当的模-数-模转换器及其它元件，实现通信装置之间的通信。利用被称为“收发器”的硬件元件来实现通信。移动装置可能具有一个以上的收发器，能够在不同的网络上进行通信。例如，蜂窝电话可包括用于与蜂窝基站通信的蜂窝收发器、用于与Wi-Fi网络通信的Wi-Fi收发器、以及用于与蓝牙（RTM）装置通信的蓝牙（RTM）收发器。可经由“接入点”来访问Wi-Fi网络，接入点例如为无线路由器，能够与Wi-Fi收发器进行通信来发送及接收数据。Wi-Fi网络还可以连接到因特网或其它基于分组的网络。网络连接或接入点的“带宽”是对数据传输率的测量指标，可被表示为每单位时间传输的数据量。The mobile devices communicate with each other or with other components via a network, such as a wireless network or a wired network. A "network" may include broadband wide area networks such as cellular networks, local area networks (LAN), wireless LANs (Wi-Fi), and personal area networks such as near field communication (NFC) networks including Bluetooth (RTM). Communications on the network are preferably packet-based; however, radio FM/AM networks may enable communication between communicating devices using appropriate analog-to-digital-to-analog converters and other components. Communication is accomplished using a hardware element called a "transceiver". A mobile device may have more than one transceiver capable of communicating on different networks. For example, a cellular telephone may include a cellular transceiver for communicating with a cellular base station, a Wi-Fi transceiver for communicating with a Wi-Fi network, and a Bluetooth (RTM) transceiver for communicating with a Bluetooth (RTM) device. A Wi-Fi network may be accessed via an "access point," such as a wireless router, that is capable of communicating with a Wi-Fi transceiver to send and receive data. A Wi-Fi network can also connect to the Internet or other packet-based networks. The "bandwidth" of a network connection or access point is a measure of data transfer rate, expressed as the amount of data transferred per unit of time.
网络通常包括配备有用于在网络上执行任务的逻辑的多个网元。逻辑可设置于服务器上。在当前的基于分组的广域网中，服务器可被设在网络上的几个逻辑点处。服务器还可与数据库进行通信，可以使通信装置能够访问数据库的内容。计费服务器、应用服务器等是这样的服务器的例子。一个服务器可包括几个网元，包括其它服务器，并可逻辑上位于服务提供者的网络上的任何地方，例如蜂窝网络的后端。服务器设有数据库或者与数据库通信，该数据库含有移动装置的用户的账户。“用户账户”包括特定用户的几种属性，包括用户所拥有的移动装置的唯一标识符、与其他用户之间的关系、应用使用、位置、个人设置、业务规则、银行账户及其它信息。服务器可以与不同网络上的其它服务器进行通信，以更新用户账户。A network typically includes a number of network elements equipped with logic for performing tasks on the network. The logic can be located on the server. In current packet-based wide area networks, servers can be located at several logical points on the network. The server may also be in communication with the database and may enable the communication device to access the contents of the database. Billing servers, application servers, etc. are examples of such servers. A server may comprise several network elements, including other servers, and may be located logically anywhere on the service provider's network, such as the back end of a cellular network. The server is provided with or is in communication with a database containing accounts of users of the mobile devices. A "User Account" includes several attributes of a particular User, including unique identifiers for mobile devices owned by the User, relationships with other Users, application usage, location, personal settings, business rules, bank accounts, and other information. The server may communicate with other servers on different networks to update user accounts.
这里及全文中使用的“位置”一词是指由一个或多个网络服务的任何物理位置。移动装置具有可通过多种方法来确定的“位置”，这些方法例如为全球定位系统（GPS）、辅助GPS（A-GPS）、蜂窝塔三角测量、RF签名等，下面会描述。道路上的车道可以是一个位置。收费站可以是一个位置。位置可包括地理围栏（geo-fence）。地理围栏是在一个位置周边的虚拟周界，以便当一辆智能车进入或离开该位置时，产生一个通知。可以利用通过从基站/蜂窝塔的信号测量进行的无线定位、利用GPS/A-GPS、或者利用与NFC收发器的靠近程度来确定位置。位置的区域可以由NFC收发器的数量和范围来控制。确定随时间而变的位置实现了对移动速率或速度的测量。The term "location" as used herein and throughout refers to any physical location served by one or more networks. Mobile devices have a "location" that can be determined by a variety of methods such as Global Positioning System (GPS), Assisted GPS (A-GPS), cell tower triangulation, RF signatures, etc., as described below. A lane on a road can be a location. A toll booth can be a location. Locations may include geo-fences. A geofence is a virtual perimeter around a location so that a notification is generated when a smart car enters or leaves the location. Location can be determined using wireless positioning through signal measurements from base stations/cell towers, using GPS/A-GPS, or using proximity to NFC transceivers. The area of the location can be controlled by the number and range of NFC transceivers. Determining position over time enables the measurement of rate of movement or velocity.

The mobile device 101 includes a speaker 102 , a display 103 , a microphone 105 and an antenna 107 . The mobile device 101 also includes a network interface (NIC) 109 , a Wi-Fi transceiver 111 , a global positioning system (GPS) receiver 113 , a power source 115 , a central processing unit (CPU) 117 and a memory 119 . The speaker 102 provides audio output for the mobile device 101 . The display 103 is an LCD or LED or other type of display on which the user can see options, numbers, letters, etc. The display 103 may also be a touch screen, thereby serving as an input device. In embodiments that do not use a touch screen, the keypad is typically used as an input device, eg, to enter a phone number or message. Such a keypad may be a numeric keypad, a QWERTY keyboard, or the like. The microphone 105 allows the user to communicate with other people using the mobile device 101 by voice. The antenna 107 is a transducer designed to send and receive electromagnetic waves to and from the network. Along with antenna 107, network interface 109 allows wireless communication between mobile device 101 and a cellular network, or with other wireless devices over the cellular network. Network interface 109 may be a cellular transceiver, a wireless transceiver, etc., and includes a combination of various transceivers that communicate with various wireless networks. The Wi-Fi transceiver 111 enables the mobile device 101 to communicate wirelessly with a Wi-Fi access point within a short range and through the access point with a packet-based network such as the Internet and other devices on the Internet. The GPS transceiver 113 enables the location of the mobile device 101 to be determined by receiving signals from GPS satellites. In addition to these signals, the network interface 109 may receive assistance data from an A-GPS server on the cellular network, thereby enabling the GPS receiver 113 to "lock" to satellite signals more quickly. The power supply 115 provides power to each component of the mobile device 101 and may include a battery and an interface to an external power source. CPU 117 controls the components of mobile device 101 according to instructions stored in logic on memory 119 . Memory 119 includes any computer-readable media, such as RAM, ROM, and the like. Memory 119 stores logic 112 in addition to logic used to run components of mobile device 101 . The memory 119 also stores a database comprising a set of rules, such as defined time blocks that determine when a Wi-Fi transceiver needs to be activated or deactivated, and also stores Wi-Fi access times corresponding to predefined locations. point database. The contents of the database 114 may be specified by the operator of the cellular network, or may be added to the database 114 based on usage of the device 101 as the device 101 visits different access points in different locations.
逻辑112一直监视着多个条件，这些条件用于确定Wi-Fi收发器111是否需要被激活、以及移动装置101是否需要通过Wi-Fi网络而不是蜂窝网络来通信。如上所述，存在几种触发并启用Wi-Fi接入点的智能选择的条件的组合。通常如下所述。首先，参考一个时间表来确定Wi-Fi收发器111何时将被激活并用于连接到Wi-Fi接入点。对于有些用户而言这种最简单的选项是有用的，这些用户希望根据可预测的时间安排（例如按照他们到访的位置）来激活他们的Wi-Fi收发器，从而根据他们很可能会去的地方，按规定的时间间隔连接到Wi-Fi接入点。例如，用户可以将移动装置设置为仅在每晚他们通常在家的时间寻找Wi-Fi。时间表可通过用户接口来编写，并被存储在数据库114中或者网络上的用户账户中。The logic 112 is constantly monitoring a number of conditions for determining whether the Wi-Fi transceiver 111 needs to be activated and whether the mobile device 101 needs to communicate over the Wi-Fi network instead of the cellular network. As mentioned above, there are several combinations of conditions that trigger and enable smart selection of Wi-Fi access points. Usually as follows. First, a schedule is referenced to determine when the Wi-Fi transceiver 111 will be activated and used to connect to the Wi-Fi access point. This simplest option is useful for users who want to activate their Wi-Fi transceivers on a predictable schedule, such as where they place, connect to the Wi-Fi access point at regular intervals. For example, a user may set a mobile device to only look for Wi-Fi each night at times when they are usually at home. Schedules can be programmed through the user interface and stored in the database 114 or in the user's account on the network.
连接到Wi-Fi接入点的第二种触发方式是使用RF指纹辅助激活。Wi-Fi收发器111根据何时发觉已知的RF指纹而被激活。这是一种使用由NIC109接收的蜂窝信号的RF指纹来确定移动装置101处于特定的已知位置的基于位置的服务。RF指纹由NIC109相当容易地测量到，这是因为NIC109一直在搜寻来自服务于移动装置101当前所在的区域的蜂窝塔的信号。当NIC109扫描寻找蜂窝信号时，它还与信号一同接收信号强度、时序（timing）以及一定量的噪声。这可能包括例如分贝数（相对于公差或阈值）、信号与噪声干扰比（SNIR）等。此外，来自多个蜂窝塔的多个信号被组合在一起，建立蜂窝扇区，下面将参考图4来描述。这种特性组合为移动装置101被使用时所处的蜂窝扇区内的特定位置提供了唯一的RF指纹。例如，办公楼将与停车场有不同的RF签名，虽然这两个位置都由同一蜂窝扇区服务。因此，一个具体的RF签名可以与特定的位置相关联，任何可用的Wi-Fi接入点可以与该特定位置相关联。The second trigger by connecting to a Wi-Fi access point is using RF Fingerprint Assisted Activation. The Wi-Fi transceiver 111 is activated upon seeing a known RF fingerprint. This is a location-based service that uses the RF fingerprint of cellular signals received by the NIC 109 to determine that the mobile device 101 is at a particular known location. RF fingerprints are fairly easily measured by the NIC 109 because the NIC 109 is always looking for signals from cell towers serving the area where the mobile device 101 is currently located. When the NIC 109 scans for a cellular signal, it also receives signal strength, timing, and a certain amount of noise along with the signal. This may include, for example, decibel numbers (relative to a tolerance or threshold), signal-to-noise-to-interference ratio (SNIR), etc. Additionally, multiple signals from multiple cellular towers are combined to create cellular sectors, as described below with reference to FIG. 4 . This combination of properties provides a unique RF fingerprint for a particular location within the cell sector in which the mobile device 101 is being used. For example, an office building will have a different RF signature than a parking lot, although both locations are served by the same cellular sector. Thus, a specific RF signature can be associated with a specific location, and any available Wi-Fi access points can be associated with that specific location.
特定位置的RF签名可以预先定义并存储在数据库中，例如数据库114或者蜂窝网络上的服务器中的数据库。或者，可以基于其他用户关于该特定位置的体验来修改及附加RF签名。产生时间上的平均RF指纹，其可用于在位置与该区域中可用的Wi-Fi接入点之间建立关联。可以在移动装置自身上建立关联，在这种情况下，已知的RF指纹、对应的位置及相关联的Wi-Fi接入点被周期性地下载到数据库114中。或者，在网络上建立关联，其中移动装置101将RF签名发送到网络上的服务器，并接收要连接到的接入点的列表。在任一种情况下，一旦确定RF签名对应于具有一个或多个可用的Wi-Fi接入点的位置，则移动装置101上的逻辑或者网络上的服务器中的逻辑命令Wi-Fi收发器111连接到适当的Wi-Fi接入点。The location-specific RF signatures may be predefined and stored in a database, such as database 114 or a database in a server on the cellular network. Alternatively, the RF signature may be modified and appended based on other users' experience with that particular location. A time-averaged RF fingerprint is generated that can be used to correlate a location with Wi-Fi access points available in the area. The association may be established on the mobile device itself, in which case known RF fingerprints, corresponding locations and associated Wi-Fi access points are periodically downloaded into the database 114 . Alternatively, an association is established on the network where the mobile device 101 sends the RF signature to a server on the network and receives a list of access points to connect to. In either case, upon determining that the RF signature corresponds to a location with one or more available Wi-Fi access points, logic on the mobile device 101 or in a server on the network commands the Wi-Fi transceiver 111 Connect to an appropriate Wi-Fi access point.
在替换实施例中，激活Wi-Fi收发器111，检测到可用的Wi-Fi接入点，然后Wi-Fi收发器111被停用并且继续经由NIC109的正常蜂窝传输，直到启动一个高带宽应用为止。只有在需要额外的带宽时才激活Wi-Fi，从而在绝对必要前一直节省电池。本发明还提出从网络上的服务器自动刷新接入点列表。本地存储的列表可被定期清除并替换为更新的列表，例如每隔30天或90天。In an alternate embodiment, the Wi-Fi transceiver 111 is activated, an available Wi-Fi access point is detected, then the Wi-Fi transceiver 111 is deactivated and normal cellular transmissions continue via the NIC 109 until a high bandwidth application is launched until. Only activate Wi-Fi when you need the extra bandwidth, saving battery until absolutely necessary. The invention also proposes to automatically refresh the list of access points from a server on the network. The locally stored list may be cleared and replaced with a newer list periodically, such as every 30 or 90 days.
第三种智能连接到Wi-Fi接入点的方式为使用基于随选位置的系统。这样系统的一个例子为AT&T的网络事件位置系统（NELOS），其在美国专利申请12/712,424中进行了描述，该申请的内容全文合并到本文中。简要地说，通过确定一个或多个小区站点和移动装置之间的传播延迟来得到信号路径补偿。这样的确定至少部分基于在整个覆盖扇区或小区中的移动装置的位置的统计分析。可以通过无线信号的指纹定位（TFL）测量来生成位置。一组参考架（referenceframe）中的每个参考架都与一对小区站点相关，该组参考架与一组具有预定粒度的地理网格框架架位置相关。这使得能够比传统方法（例如三角测量法）更精确地确定移动装置101的位置。结果，蜂窝网络获知移动装置101的精确位置，并且网络上的服务器配备有基于该位置触发Wi-Fi收发器111的激活的逻辑。A third way to intelligently connect to a Wi-Fi access point is to use an on-demand location-based system. An example of such a system is AT&T's Network Event Location System (NELOS), which is described in US patent application Ser. No. 12/712,424, the contents of which are incorporated herein in their entirety. Briefly, signal path compensation is obtained by determining the propagation delay between one or more cell sites and a mobile device. Such a determination is based at least in part on a statistical analysis of the location of the mobile device throughout the coverage sector or cell. Locations can be generated by fingerprint localization (TFL) measurements of wireless signals. Each reference frame is associated with a pair of cell sites in a set of reference frames associated with a set of geographic grid frame positions with a predetermined granularity. This enables a more precise determination of the location of the mobile device 101 than conventional methods such as triangulation. As a result, the cellular network knows the precise location of the mobile device 101, and the servers on the network are equipped with logic to trigger the activation of the Wi-Fi transceiver 111 based on that location.
遵从移动装置101的用户和网络运营商之间的任何预先合约，网络上（例如，应用服务器上）的逻辑有能力覆写任何用户设置，并依据有关移动装置101正在吞吐多少数据的网络层确定结果来打开或启用Wi-Fi收发器111。网络实体还有能力停用Wi-Fi收发器111并切换回使用NIC109的通信。这项特征特别有用，例如当对于移动装置101恰好所在的位置上的特定Wi-Fi接入点需要生成性能报告的“快照”时。这是上面描述的动态智能的一个例子，为网络运营商提供了动态控制有多少装置正在访问不同的网络接入点并均匀地分配负载的能力。这种智能还可以扩展到命令多个移动装置提交由网络运营商确定的特定位置上的Wi-Fi接入点可用性的多个报告。得到的报告可被用于产生网络的Wi-Fi覆盖的“地图”。与上述小区站点的RF指纹的信息合在一起，这为网络运营商提供了对于他们的网络有多少不同方面正在运行的更高程度的认知。Subject to any pre-contract between the user of the mobile device 101 and the network operator, the logic on the network (e.g., on the application server) has the ability to override any user settings, based on network layer determinations about how much data the mobile device 101 is throughput As a result, the Wi-Fi transceiver 111 is turned on or enabled. The network entity also has the ability to deactivate the Wi-Fi transceiver 111 and switch back to communication using the NIC 109 . This feature is particularly useful, for example, when a "snapshot" of a performance report needs to be generated for a particular Wi-Fi access point at the location where the mobile device 101 happens to be. This is an example of the dynamic intelligence described above, providing network operators with the ability to dynamically control how many devices are accessing different network access points and distribute the load evenly. This intelligence can also be extended to command multiple mobile devices to submit multiple reports of Wi-Fi access point availability at a particular location as determined by the network operator. The resulting reports can be used to generate a "map" of the network's Wi-Fi coverage. Taken together with the aforementioned information on the RF fingerprints of the cell sites, this provides network operators with a higher degree of awareness of how many different aspects of their network are operating.
智能选择Wi-Fi接入点的第四种方法是通过侦听从蜂窝网络接收的蜂窝广播来启动Wi-Fi收发器111的激活。这可被称为“辅助Wi-Fi激活”。简要地说，蜂窝网络采用可在任何蜂窝系统上传输的极低带宽信道。广播被发送到在可见的扇区或小区站点内的所有移动装置，并包括短消息系统（SMS）或多媒体广播多播服务（MBMS）。所广播的信息包括覆盖区内的所有可用的Wi-Fi接入点。蜂窝扇区越小，接收广播的移动装置位于接入点范围内的可能性越大。这可以独立使用，或可以与上述其它方法，例如RF指纹法等一起使用。例如，广播可以包括特定接入点的坐标（经度、纬度、或与此相当的坐标系），移动装置101可以基于其自身位置的确定来挑选最近的接入点。这实现了对网络的理想优化，使蜂窝带宽的使用最少。A fourth method of intelligently selecting a Wi-Fi access point is to initiate the activation of the Wi-Fi transceiver 111 by listening to cellular broadcasts received from the cellular network. This may be referred to as "assisted Wi-Fi activation". Briefly, cellular networks employ extremely low bandwidth channels that can be transmitted over any cellular system. Broadcasts are sent to all mobile devices within a visible sector or cell site and include Short Message System (SMS) or Multimedia Broadcast Multicast Service (MBMS). The broadcasted information includes all available Wi-Fi access points in the coverage area. The smaller the cell sector, the more likely the mobile device receiving the broadcast is within range of the access point. This can be used on its own, or it can be used in conjunction with other methods mentioned above, such as RF fingerprinting and the like. For example, the broadcast may include the coordinates (longitude, latitude, or equivalent coordinate system) of a particular access point, and the mobile device 101 may pick the closest access point based on a determination of its own location. This achieves ideal optimization of the network with minimal use of cellular bandwidth.
用于智能Wi-Fi接入点选择的第五种方法涉及位置获知Wi-Fi激活，即，只要移动装置101知道了（通过GPS或其他方法）它在某个接入点附近，那么就激活Wi-Fi收发器111。可以通过启动基于位置的服务应用，例如地图、导航等，来触发位置获知。在任一种情况下，只要移动装置知道了自己的位置，就可以与数据库114或网络上的数据库建立关联，并且可以连接到可用的Wi-Fi接入点。通常，GPS接收器113被用于确定移动装置101的位置。利用该特征，可以容易地获取以下信息：服务区（城市、州、国家）、位置（经度、纬度、街道号）、移动速度等等。服务区信息被用来判断移动装置是否处于服务控制区内。对于没有GPS接收器的装置来说，蜂窝塔位置ID（小区ID）可被用于精度稍差的测量。基于蜂窝塔的定位可以提供这样的信息。A fifth method for intelligent Wi-Fi access point selection involves location-aware Wi-Fi activation, i.e., whenever the mobile device 101 knows (via GPS or otherwise) that it is near an access point, then activates Wi-Fi transceiver 111. Location learning can be triggered by launching location-based service applications, such as maps and navigation. In either case, once the mobile device knows its location, it can establish an association with the database 114 or a database on the network, and can connect to an available Wi-Fi access point. Typically, a GPS receiver 113 is used to determine the location of the mobile device 101 . Using this feature, the following information can be easily obtained: service area (city, state, country), location (longitude, latitude, street number), moving speed, etc. The service area information is used to determine whether the mobile device is within the service control area. For devices without a GPS receiver, the cell tower location ID (cell ID) can be used for less accurate measurements. Cell tower-based positioning can provide such information.
在本发明的示例性实施例中，只有当超过了阈值带宽或数据传输率时，或者在启动了高带宽应用的情况下，上述各种激活方法才被触发。在移动装置101上的逻辑激活Wi-Fi收发器111，或者网络上的应用服务器中的逻辑启动激活过程。在其它实施例中，每次Wi-Fi收发器111被激活并对位置进行扫描以寻找Wi-Fi接入点时，就动态更新应用服务器上的数据库。有关可用的Wi-Fi接入点、它们的信号强度及可用性的报告被从多个移动装置发送到网络，该信息被用于建立接入点的数据库。此外，可以基于移动装置所测量的性能级别，对接入点进行排名，接下来的连接到Wi-Fi接入点的命令可具体到连接到排名最高的接入点。In an exemplary embodiment of the present invention, the various activation methods described above are triggered only when a threshold bandwidth or data transfer rate is exceeded, or when a high-bandwidth application is activated. Logic on the mobile device 101 activates the Wi-Fi transceiver 111, or logic in an application server on the network initiates the activation process. In other embodiments, the database on the application server is dynamically updated each time the Wi-Fi transceiver 111 is activated and scans locations for Wi-Fi access points. Reports are sent from multiple mobile devices to the network about available Wi-Fi access points, their signal strength and availability, and this information is used to build a database of access points. Furthermore, the access points can be ranked based on the performance level measured by the mobile device, and subsequent commands to connect to the Wi-Fi access point can be specific to connect to the highest ranked access point.
逻辑112还收集诸如移动装置101的速度（也可以通过GPS接收器113来获取）一类的信息，并根据测量的速度确定一个特定的接入点就要连不上了，因为它将在几秒后失去信号。例如，沿公路的快速移动可能足以确定移动装置101应当留在蜂窝网络中，而不连接到接入点，尽管它排名很高，这是因为移动装置处于移动中，也许将丢失Wi-Fi信号。通常，上述条件的不同组合可取决于不同的服务需求，例如，目标用户、控制精度、控制灵活性等。也可能由于实施复杂性而受到限制。The logic 112 also collects information such as the speed of the mobile device 101 (which can also be obtained by the GPS receiver 113), and based on the measured speed, determines that a particular access point is about to fail because it will be in a few minutes. The signal is lost after seconds. For example, a quick move along a highway may be enough to determine that the mobile device 101 should stay on the cellular network and not connect to an access point, even though it ranks high because the mobile device is on the move and will probably lose Wi-Fi signal . Generally, different combinations of the above conditions may depend on different service requirements, for example, target users, control precision, control flexibility, and the like. May also be limited due to implementation complexity.
图2根据本发明的一个示例性实施例示出了用于Wi-Fi接入点智能选择的系统200。移动装置201位于接入点221和223的范围内，每个接入点具有各自的范围222和224。移动装置201还经由蜂窝收发器与蜂窝塔230通信，蜂窝塔230是基站（或UMTS系统中的节点B）的一部分。蜂窝塔230提供对蜂窝网络231的接入，蜂窝网络231的元件是本领域已知的，因此未示出。位于蜂窝网络231后端的是容纳有数据库242的应用服务器241。接入点221、223可以是Wi-Fi收发器、飞蜂窝等。接入点221、223为移动装置201提供对基于分组的网络（例如因特网和/或蜂窝网络231）的访问。在飞蜂窝的情况下，移动装置201将使用蜂窝收发器与飞蜂窝进行通信，但是该通信仍能缓解可经由蜂窝塔230访问的蜂窝网络231的各元件的负担。Fig. 2 shows a system 200 for intelligent selection of Wi-Fi access points according to an exemplary embodiment of the present invention. Mobile device 201 is within range of access points 221 and 223 , each with a respective range 222 and 224 . The mobile device 201 also communicates via a cellular transceiver with a cellular tower 230, which is part of a base station (or Node B in UMTS systems). Cellular tower 230 provides access to cellular network 231, the elements of which are known in the art and are therefore not shown. Sitting behind the cellular network 231 is an application server 241 housing a database 242 . Access points 221, 223 may be Wi-Fi transceivers, femtocells, or the like. Access points 221 , 223 provide mobile device 201 with access to packet-based networks, such as the Internet and/or cellular network 231 . In the case of a femtocell, the mobile device 201 would use a cellular transceiver to communicate with the femtocell, but the communication would still offload elements of the cellular network 231 accessible via the cellular tower 230 .
在运行中，移动装置201上的Wi-Fi收发器一开始处于非活动状态以省电。在移动装置201或应用服务器241上的逻辑一直监视着用于确定是否需要激活移动装置201上的Wi-Fi收发器的多个条件。通常，接入点221、223可以位于相同的位置/小区站点，但具有不同的范围222、224。移动装置201经由塔230将上述位置报告给服务器241。服务器241基于移动装置201的精确位置与接入点221、223的位置的相关性来确定接入点221排名高于接入点223。此外，上述排名系统可用于在接入点221、223和蜂窝塔230之间进行动态选择。如上所述，存在几种触发并启用Wi-Fi接入点221、223的智能选择的条件组合。例如，可由移动装置201的用户来定义时间表，如果日期时间落入时间表的一部分内，则开始动态选择。In operation, the Wi-Fi transceiver on the mobile device 201 is initially inactive to save power. Logic on the mobile device 201 or the application server 241 is constantly monitoring a number of conditions for determining whether the Wi-Fi transceiver on the mobile device 201 needs to be activated. Typically, the access points 221 , 223 may be located at the same location/cell site, but have different ranges 222 , 224 . The mobile device 201 reports the aforementioned location to the server 241 via the tower 230 . The server 241 determines that the access point 221 is ranked higher than the access point 223 based on the correlation of the precise location of the mobile device 201 with the locations of the access points 221 , 223 . Additionally, the ranking system described above can be used to dynamically select between access points 221, 223 and cell towers 230. As mentioned above, there are several combinations of conditions that trigger and enable the intelligent selection of the Wi-Fi access point 221, 223. For example, a schedule may be defined by the user of the mobile device 201, and if the date-time falls within a portion of the schedule, dynamic selection begins.
RF指纹可用于辅助Wi-Fi收发器的激活。一个或多个塔230的RF指纹由移动装置201来测量，被发送给服务器241，并与数据库242中的已知位置建立关联。根据确定在一个已知位置有对应的可用接入点来激活Wi-Fi收发器。此外，可以基于其他用户对于该具体位置的体验来修改及添附RF签名。一旦确定RF签名对应于具有一个或多个可用Wi-Fi接入点的位置，在移动装置201或者网络上的逻辑就命令Wi-Fi收发器连接到适当的Wi-Fi接入点221或223。此外，基于随选位置的系统提供移动装置201的详细位置，这在NELOS专利申请中进行了描述。从塔230接收的蜂窝广播还可以帮助接入点221、223的选择。所广播的信息包括可用Wi-Fi接入点的清单，移动装置201可以基于其自身位置的确定结果以及接入点的性能级别来挑选最近的接入点。最后，只要移动装置201获知了其精确位置（例如通过GPS或A-GPS），就与数据库242或移动装置201上的数据库进行关联，并且激活Wi-Fi收发器。RF fingerprinting can be used to aid in the activation of Wi-Fi transceivers. The RF fingerprints of one or more towers 230 are measured by mobile device 201 , sent to server 241 , and associated with known locations in database 242 . The Wi-Fi transceiver is activated upon determining that there is a corresponding available access point at a known location. Furthermore, RF signatures can be modified and appended based on other users' experiences with that particular location. Once it is determined that the RF signature corresponds to a location with one or more available Wi-Fi access points, logic on the mobile device 201 or network commands the Wi-Fi transceiver to connect to the appropriate Wi-Fi access point 221 or 223 . Additionally, a location-on-demand based system provides the detailed location of the mobile device 201, which is described in the NELOS patent application. Cellular broadcasts received from the tower 230 may also aid in the selection of the access point 221,223. The broadcasted information includes a list of available Wi-Fi access points, and the mobile device 201 can pick the closest access point based on the determination of its own location and the performance level of the access points. Finally, whenever the mobile device 201 knows its precise location (for example via GPS or A-GPS), it associates with the database 242 or a database on the mobile device 201 and activates the Wi-Fi transceiver.
图3根据本发明的一个示例性实施例示出了用于Wi-Fi接入点的智能选择的系统。系统300基本上与系统200相同，只是增加了GPS卫星348，它发射信号349。信号349由移动装置301上的GPS接收器接收，能够实现精确位置估计。来自蜂窝网络331上的A-GPS服务器（未示出）的辅助数据可通过塔330来传送。如上所述，移动装置301将位置报告给应用服务器341。如上所述，几种额外的条件组合触发并启用Wi-Fi接入点321、323之一的智能选择。可从服务器341上的动态智能部分向移动装置301命令其它特征（例如Wi-Fi性能测试等）。Fig. 3 shows a system for intelligent selection of Wi-Fi access points according to an exemplary embodiment of the present invention. System 300 is essentially the same as system 200 with the addition of GPS satellites 348 which emit signals 349 . Signal 349 is received by a GPS receiver on mobile device 301, enabling precise location estimation. Assistance data from an A-GPS server (not shown) on cellular network 331 may be transmitted through tower 330 . As mentioned above, the mobile device 301 reports the location to the application server 341 . As mentioned above, several additional combinations of conditions trigger and enable intelligent selection of one of the Wi-Fi access points 321, 323. Other features (eg, Wi-Fi performance tests, etc.) can be commanded to the mobile device 301 from the dynamic intelligence on the server 341 .
图4根据本发明的一个示例性实施例示出了利用RF指纹进行智能接入点选择的系统。三个蜂窝塔430、431和432使用径向指向彼此不同的一个或多个天线各自覆盖区域433。应当理解，网路布局可以涵盖任意数量的区域433。此外，区域433被显示为六边形；然而，覆盖小区可以采用其它几何形状，通常用布局结构、位置等来表示。两个塔可以使用链路（例如线缆、端口、交换机、连接器等）耦合在一起，形成一对。无线电网络控制器（未示出）可以是包含塔430、431和432的无线电接入网（RAN）的一部分。RNC可以分布在该组塔430、431、432或相关联的基站/节点B设施当中。蜂窝扇区435由塔430、431和432形成，移动装置401可以通过通信链路430a、431a和432a分别与每个塔进行通信。FIG. 4 shows a system for intelligent access point selection using RF fingerprints according to an exemplary embodiment of the present invention. Three cell towers 430, 431, and 432 each cover area 433 using one or more antennas that are radially directed differently from each other. It should be understood that the network layout may cover any number of areas 433 . Additionally, area 433 is shown as a hexagon; however, coverage cells may take other geometries, typically represented by layout structures, locations, and the like. Two towers can be coupled together using a link (eg, cable, port, switch, connector, etc.) to form a pair. A radio network controller (not shown) may be part of a radio access network (RAN) comprising towers 430 , 431 and 432 . The RNCs may be distributed among the set of towers 430, 431, 432 or associated base station/Node B facilities. Cellular sector 435 is formed by towers 430, 431, and 432, with which mobile device 401 can communicate via communication links 430a, 431a, and 432a, respectively.
移动装置401通过调谐到扇区435中存在的每个信号430a、431a和432a来测量RF指纹。对信号强度、时序以及相对于信号的一定量的噪声（例如SNIR）进行测量。无线信号的时序考虑了从波信号产生或在塔处输出直至在移动装置401检出为止的时间。这样的时间包括穿过链路到达天线的基站时间以及在空中接口或无线信道上的传播时间。时延一般起源于多个源，例如电子元件和组件当中的失配（阻抗失配）、寄生电容和电感、基站中的天线线缆的长度、塔高度、多径、反射等。对于扇区435内的每个精确位置（确定至粒度），都要测量唯一的RF指纹。可通过一组参考架来确定精确位置，每个参考架与一对小区站点相关，并使该组参考架与具有预定粒度的一组地理网格框架架位置相关，如NELOS专利所述。测得的RF签名可与特定位置相关联，并且任何可用的Wi-Fi接入点421、423都与该特定位置相关联。基于其他用户对于该特定位置的体验来修改或添附RF签名。产生时间上的平均RF指纹，其可被用于使位置与该区域中可用的Wi-Fi接入点建立相关。可以在移动装置自身上进行相关建立，在这种情况下，已知的RF指纹、对应的位置以及相关联的Wi-Fi接入点被周期性地下载到装置401。或者，在网络中进行相关建立，移动装置401将RF签名发送到网路上的服务器并接收要连接到的接入点的列表。在任一种情况下，一旦确定RF签名对应于具有一个或多个可用Wi-Fi接入点的位置，移动装置401中的Wi-Fi收发器就被命令连接到适当的Wi-Fi接入点421、423。The mobile device 401 measures the RF fingerprint by tuning to each of the signals 430 a , 431 a , and 432 a present in the sector 435 . Measures signal strength, timing, and an amount of noise (eg SNIR) relative to the signal. The timing of the wireless signal takes into account the time from when the wave signal is generated or output at the tower until detected at the mobile device 401 . Such times include the base station time across the link to the antenna and the propagation time over the air interface or radio channel. Latency typically arises from multiple sources such as mismatches (impedance mismatches) among electronic components and assemblies, parasitic capacitance and inductance, length of antenna cables in base stations, tower heights, multipath, reflections, etc. For each precise location (determined to granularity) within sector 435, a unique RF fingerprint is measured. The precise location can be determined by a set of reference frames, each associated with a pair of cell sites, and relating the set of reference frames to a set of geographic grid frame positions with a predetermined granularity, as described in the NELOS patent. The measured RF signature may be associated with a particular location, and any available Wi-Fi access points 421, 423 are associated with that particular location. The RF signature is modified or appended based on other users' experiences with that particular location. A time-averaged RF fingerprint is generated that can be used to correlate location with Wi-Fi access points available in the area. The correlation establishment may be done on the mobile device itself, in which case the known RF fingerprints, corresponding locations and associated Wi-Fi access points are downloaded to the device 401 periodically. Alternatively, the association is set up in the network, the mobile device 401 sends the RF signature to a server on the network and receives a list of access points to connect to. In either case, once it is determined that the RF signature corresponds to a location with one or more Wi-Fi access points available, the Wi-Fi transceiver in the mobile device 401 is commanded to connect to the appropriate Wi-Fi access point 421, 423.
图5根据本发明的一个示例性实施例示出了用于接入点智能选择的方法。如上所述，在移动装置或网络上的逻辑一直监视着多个条件，这些条件用于确定是否需要激活Wi-Fi收发器、或者移动装置是否需要通过Wi-Fi网络而不是蜂窝网络进行通信。在步骤S550，监视当前日期时间。在步骤S551，将当前时间与时间表相比较，以判断是否有可用的接入点以及是否连接到该接入点。具有可预测的时间表的用户可以使用该时间表选项，所述可预测的时间表例如为用户什么时间下班回家，或者想要在家使用飞蜂窝或其他收发器的人也可以使用该时间表选项。时间表可通过用户接口编写并存储在本地数据库或网络上。在匹配的情况下，在步骤S558激活Wi-Fi收发器/无线电部，并连接到所选的接入点。或者，无线电部可被激活，可以监视可用的接入点，然后在不连接的情况下停用。这有助于在指定的时间获知可用接入点，使得如果检测到任何其它触发，则可以按需接入可用的接入点。在特定的时间块期间可以为特定的接入点设置一个标志，该标志被存储在本地或网络数据库中。这有可能节省电池电能，以供未来在该时间块内的使用。Fig. 5 shows a method for intelligent selection of access points according to an exemplary embodiment of the present invention. As mentioned above, logic on the mobile device or network is constantly monitoring a number of conditions to determine whether the Wi-Fi transceiver needs to be activated, or whether the mobile device needs to communicate over the Wi-Fi network rather than the cellular network. In step S550, monitor the current date and time. In step S551, the current time is compared with the time table to determine whether there is an available access point and whether to connect to the access point. This schedule option can be used by users who have a predictable schedule, such as when the user comes home from get off work, or who want to use a femtocell or other transceiver at home option. Schedules can be written through the user interface and stored in a local database or on the network. In the case of a match, the Wi-Fi transceiver/radio is activated at step S558 and connects to the selected access point. Alternatively, the radio can be activated, can monitor available access points, and then deactivated without connecting. This helps to know available access points at a specified time so that if any other trigger is detected, available access points can be accessed on demand. A flag can be set for a particular access point during a particular time block, which flag is stored in a local or network database. This potentially saves battery power for future use during that time block.
在步骤S552，估计带宽需求。这可以通过由蜂窝收发器来监视吞吐率、或者通过监视一个或多个应用在移动装置上的使用情况来实现。如果在S554吞吐率超过了定义的阈值，则在S558激活Wi-Fi，否则需要其它触发条件来触发智能。这有助于在非必要情况下节省电力。在步骤S555，估计移动装置的位置。如上所述，这可以用几种方法中的一种或多种方法来实现。例如，使用蜂窝收发器来测量已知的RF指纹，并且使该RF指纹与特定位置相关联，任何可用的Wi-Fi接入点都可以与该特定位置相关联。如果在S557的相关返回肯定结果，则激活无线电部。或者，采用基于随选位置的系统，例如在NELOS专利申请中描述的那样。或者，从蜂窝网络接收的蜂窝广播提供该特定位置的可用接入点的列表。广播被发送到可见的扇区或小区站点内的所有移动装置，并且包括短消息系统（SMS）或多媒体广播多播服务（MBMS）。这可以独立使用，或者与上述其它方法（例如RF指纹法）一起使用。或者，只要移动装置获知（通过GPS或其它方法）它位于某接入点附近，则触发步骤S558的智能。通常，只要在S555估计的位置和包含S557处的接入点的已知位置之间存在相关，则可以在S558处激活无线电部。另外，可以仅在步骤S552处超过了阈值带宽或数据传输率的情况下才触发这些基于位置的激活方法。In step S552, bandwidth requirements are estimated. This can be accomplished by monitoring throughput by the cellular transceiver, or by monitoring usage of one or more applications on the mobile device. If the throughput rate exceeds the defined threshold at S554, activate Wi-Fi at S558, otherwise other trigger conditions are required to trigger the intelligence. This helps to save power in non-essential situations. In step S555, the location of the mobile device is estimated. As mentioned above, this can be accomplished in one or more of several ways. For example, using a cellular transceiver to measure a known RF fingerprint and associating that RF fingerprint with a particular location, any available Wi-Fi access point can be associated with that particular location. If the correlation at S557 returns a positive result, the radio section is activated. Alternatively, a location-on-demand based system such as that described in the NELOS patent application is used. Alternatively, a cellular broadcast received from the cellular network provides a list of available access points for that particular location. Broadcasts are sent to all mobile devices within a visible sector or cell site and include Short Message System (SMS) or Multimedia Broadcast Multicast Service (MBMS). This can be used on its own, or in conjunction with the other methods mentioned above, such as RF fingerprinting. Alternatively, the intelligence of step S558 is triggered whenever the mobile device knows (via GPS or other methods) that it is in the vicinity of an access point. In general, the radio may be activated at S558 as long as there is a correlation between the estimated position at S555 and the known position including the access point at S557. Additionally, these location-based activation methods may only be triggered if a threshold bandwidth or data transfer rate is exceeded at step S552.
另外，可以基于移动装置所测量的性能级别来为接入点排名，接下来命令连接到具体为排名最高的接入点的Wi-Fi接入点。例如，由网络运营商或第三方创建的应用包括装置上逻辑，它周期性地刷新接入点的列表，并监视上述激活Wi-Fi收发器的触发条件。该应用用作连接管理器，使用例如鉴定因子来为接入点评级，所述鉴定因子是有关特定接入点的历史数据以及接入点当前的信号质量的组合。可以基于该因子为接入点排名，排名可以存储在本地和/或提交给网路上的服务器，以供将来出现在同一位置并已安装该特定应用的其它移动装置获取。这也可以扩展至未由网络运营商运营的接入点，例如非授权移动接入（UMA）接入点、公共Wi-Fi等。这些接入点也与特定位置相关联，基于鉴定因子来评级，并被添加到数据库。Additionally, the access points can be ranked based on the performance level measured by the mobile device, followed by commanding a connection to the Wi-Fi access point, specifically the highest ranked access point. For example, an application created by a network operator or a third party includes on-device logic that periodically refreshes the list of access points and monitors the aforementioned trigger conditions for activating the Wi-Fi transceiver. The application acts as a connection manager, rating access points using, for example, a qualification factor, which is a combination of historical data about a particular access point and the current signal quality of the access point. Access points can be ranked based on this factor, and the ranking can be stored locally and/or submitted to a server on the network for retrieval by other mobile devices present at the same location in the future that have installed that particular application. This can also be extended to access points not operated by the network operator, such as Unlicensed Mobile Access (UMA) access points, public Wi-Fi, etc. These access points are also associated with specific locations, rated based on the authenticator, and added to the database.
图6-10根据一个示例性实施例示出了本发明的方法的更详细步骤。图6根据本发明的一个示例性实施例示出了移动装置的正常扫描及提示模式。在该实施例中，方法开始于S660，确定是否启用智能WiFi模式。如果智能WiFi模式被启用，则智能WiFi模式被激活并在图8的点1处开始。如果智能WiFi模式未被启用，则默认模式，移动装置进入睡眠模式S661。睡眠模式可由用户或运营商通过例如用户接口的设置区来编程，并且包括设置默认睡眠时间的选项。在规定的时间期结束时，移动装置激活移动装置上的Wi-Fi收发器并扫描寻找可用的网络或接入点S662。可用的接入点被收集到列表中。随着可用的接入点被收入列表，移动装置判断是否有可用的接入点与移动装置的服务提供者所用的接入点列表相匹配。这些可以是服务提供者所运营的接入点或者以其他方式为服务提供者所知的接入点。如果有接入点与服务提供者列表（例如存储在应用服务器上的数据库中）相匹配，则移动装置进入公共连接及存储模式，见图10中的点2。如果没有接入点与服务提供者列表匹配，则逻辑判断是否找到其它接入点S664。如果没找到其它接入点，这意味着原始扫描列表为空，则该方法重新开始。如果找到了其它接入点，则移动装置判断该装置是否被授权自动连接到开放的接入点S665。该授权可由用户在接收到忽视使用开放接入点的潜在危险的提示后做出。如果移动装置被授权自动连接到开放接入点，则处理过程前进到开始于图7的点3的自动连接模式。如果移动装置未被授权自动连接到开放接入点，则该装置判断是否使用网络帮助S666。网络帮助包括例如发送给蜂窝扇区内的所有移动装置的低带宽广播。该选项可由用户预设，由用户来决定只是接收可用接入点的列表还是让蜂窝网络推荐接入点。如果启用了网络帮助，则移动装置将检测到的接入点的列表发送给网路上的服务器S667。这可以包括每个接入点的MAC地址以及信号强度及其它属性。服务器基于接收到的属性和历史数据的组合对这些接入点进行排名，并将结果发回移动装置。逻辑使Wi-Fi收发器连接到服务器所确定的排名最高的接入点。移动装置可以得到接入点的SSID、MAC地址、WiFiRSSI等。用户也可能能够看得见可用接入点的完整列表。如果网络帮助未被启用，用户被提示从排名最高的接入点中选择一个接入点S668。在该情况下，排名可基于信号强度、加密等等。在用户被提示选择接入点后，移动装置判断用户是否已选择了接入点、还是选择用的设定时间已过去了S669。例如，可以给用户1分钟，从提示时开始直至选择接入点为止。如果用户选择了网络，则移动装置进入公共连接及存储模式，见图10的点4。如果在用户选择接入点之前计时器已超时，则该方法重新开始。6-10 show more detailed steps of the method of the present invention according to an exemplary embodiment. FIG. 6 illustrates a normal scan and prompt mode of a mobile device according to an exemplary embodiment of the present invention. In this embodiment, the method starts at S660, determining whether to enable the smart WiFi mode. If the Smart WiFi mode is enabled, the Smart WiFi mode is activated and starts at point 1 of FIG. 8 . If the smart WiFi mode is not enabled, then the default mode, the mobile device enters the sleep mode S661. The sleep mode is programmable by the user or operator through, for example, a settings area of the user interface, and includes the option to set a default sleep time. At the end of the specified time period, the mobile device activates the Wi-Fi transceiver on the mobile device and scans for available networks or access points S662. Available access points are collected into a list. As available access points are included in the list, the mobile device determines whether any available access points match the list of access points used by the mobile device's service provider. These may be access points operated by the service provider or otherwise known to the service provider. If an access point matches the list of service providers (eg stored in a database on the application server), the mobile device enters public connection and storage mode, see point 2 in FIG. 10 . If no access point matches the service provider list, the logic determines whether other access points are found S664. If no other access points are found, meaning the original scan list is empty, the method starts over. If other access points are found, the mobile device determines whether the device is authorized to automatically connect to an open access point S665. This authorization may be made by the user after receiving a prompt to ignore the potential dangers of using an open access point. If the mobile device is authorized to automatically connect to an open access point, the process proceeds to the automatic connection mode starting at point 3 of FIG. 7 . If the mobile device is not authorized to automatically connect to an open access point, the device determines whether to use network assistance S666. Network assistance includes, for example, low bandwidth broadcasts sent to all mobile devices within a cell sector. This option can be preset by the user, and it is up to the user to just receive a list of available access points or let the cellular network recommend an access point. If web assistance is enabled, the mobile device sends a list of detected access points to a server on the network S667. This can include the MAC address of each access point as well as signal strength and other attributes. The server ranks these access points based on a combination of received attributes and historical data, and sends the results back to the mobile device. The logic causes the Wi-Fi transceiver to connect to the highest ranked access point determined by the server. The mobile device can get the SSID, MAC address, WiFi RSSI, etc. of the access point. The user may also be able to see a complete list of available access points. If web help is not enabled, the user is prompted to select an access point from among the highest ranked access points S668. In this case, the ranking may be based on signal strength, encryption, and the like. After the user is prompted to select an access point, the mobile device determines whether the user has selected an access point or whether the set time for selection has passed S669. For example, the user may be given 1 minute from when prompted until an access point is selected. If the user selects the network, the mobile device enters the public connection and storage mode, see point 4 in FIG. 10 . If the timer expires before the user selects an access point, the method starts over.
图7根据本发明的一个示例性实施例示出了移动装置的自动连接选项。在该实施例中，移动装置已被授权自动连接到开放接入点。在点3进入自动连接选项，开始时确定是否使用网络帮助S766。如果网络帮助选项不被启用，则移动装置接着按照信号强度对可用接入点的SSID进行排名（在步骤S770），信号强度例如是通过求出测得的功率相对于1毫瓦（mW）的功率比的分贝数（或dBm）。移动装置然后在点5进入公共连接及存储模式。如果网络帮助选项被启用，则移动装置将可见的接入点的列表发送给蜂窝网络上的服务器S771。这可以包括每个接入点的MAC地址。服务器对这些接入点进行排名并将结果发回移动装置，并提示用户服务器所确定的排名最高的接入点。移动装置可以得到接入点的SSID、MAC地址、WiFiRSSI等。用户还能够看见可用接入点的完整列表。此时，移动装置在点5进入公共连接及存储模式。FIG. 7 illustrates automatic connection options for a mobile device, according to an exemplary embodiment of the present invention. In this embodiment, the mobile device is authorized to automatically connect to the open access point. Enter the automatic connection option at point 3, and determine whether to use the network to help S766 at the beginning. If the network assistance option is not enabled, the mobile device then ranks (at step S770) the SSIDs of available access points by signal strength, e.g., by finding the measured power relative to 1 milliwatt (mW) Power ratio in decibels (or dBm). The mobile device then enters public connection and storage mode at point 5 . If the network assistance option is enabled, the mobile device sends a list of visible access points to the server on the cellular network S771. This can include the MAC address of each access point. The server ranks these access points and sends the results back to the mobile device, and prompts the user for the highest-ranked access point determined by the server. The mobile device can get the SSID, MAC address, WiFi RSSI, etc. of the access point. Users can also see a complete list of available access points. At this point, the mobile device enters public connection and storage mode at point 5 .
图8和图9根据本发明的一个示例性实施例示出了移动装置的智能WiFi模式。在该实施例中，在移动装置上启用智能WiFi模式，在点1移动装置进入智能WiFi模式。智能WiFi模式开始时判断是否已有让移动装置激活的命令S872。该判断可以包括在判断前的一段时间内（例如在最后5分钟内）是否出现了命令。如果已有激活的命令，那么移动装置接下来读取SSIDcom模式S873。SSIDcom是指存储优选的或排名最高的接入点的变量。在SSIDcom模式中，移动装置利用现有的接入点列表加上服务器排名的要连接到的优选/排名最高的接入点（SSIDcom）来更新临时接入点列表。移动装置然后前进到点11，在此处装置进入图9中所示的激活WiFi及扫描模式。如果还没有激活的命令，则移动装置判断接入点列表是否为空S874。由于在此模式中移动装置智能地从接入点列表中选择WiFi接入点，所以如果接入点列表为空，移动装置接下来提示用户输入接入点S875。如果列表不为空，则该装置进入睡眠模式S861。在步骤S875提示用户输入接入点时，用户被提示智能WiFi模式需要将接入点预填充在移动装置上的列表中。用户被提示输入接入点或者可以从列表中选择。关于任何现有接入点的列表被呈现给用户和/或用户能够手工输入该信息。用户也可以选择取消该输入。移动装置接下来更新任何已被选择的接入点或者将接入点加入列表中S876。8 and 9 illustrate smart WiFi modes of a mobile device according to an exemplary embodiment of the present invention. In this embodiment, Smart WiFi mode is enabled on the mobile device, and at point 1 the mobile device enters Smart WiFi mode. When the smart WiFi mode starts, it is judged whether there is a command to activate the mobile device S872. The judgment may include whether an order has occurred within a period of time (for example, within the last 5 minutes) before the judgment. If there is an active command, the mobile device next reads the SSIDcom mode S873. SSIDcom refers to a variable that stores the preferred or highest ranked access point. In SSIDcom mode, the mobile device updates the temporary access point list with the existing access point list plus the server-ranked preferred/highest-ranked access point (SSIDcom) to connect to. The mobile device then proceeds to point 11 where the device enters the active WiFi and scan mode shown in FIG. 9 . If there is no active command, the mobile device determines whether the access point list is empty S874. Since in this mode the mobile device intelligently selects a WiFi access point from the access point list, if the access point list is empty, the mobile device next prompts the user to enter an access point S875. If the list is not empty, the device enters sleep mode S861. When prompting the user to enter an access point at step S875, the user is prompted that the smart WiFi mode needs to pre-populate the list of access points on the mobile device. The user is prompted for an access point or can select from a list. A list of any existing access points is presented to the user and/or the user can manually enter this information. The user may also choose to cancel this input. The mobile device then updates any selected access points or adds access points to the list S876.
此时，移动装置前进到点8，此处移动装置回去开始正常扫描及提示模式。当装置处于睡眠模式S861时，移动装置在规定的时间段内保持在睡眠模式，例如5分钟。移动装置然后判断时间是否落入时间表中S877。用户已经预先确定了该模式工作在哪些时间段内。这可以是一周内的某天，开始小时和结束小时等。如果当前时间在允许的时间段内，则移动装置前进到SSIDcb启用比较阶段S878。如果当前时间不在允许的时间段内，则移动装置前进到点8，此处移动装置开始正常扫描及提示模式。在SSIDcb启用比较阶段S878处，移动装置确定它是否应当寻找蜂窝广播WiFi帮助。该帮助告知移动装置区域中的一个或多个接入点。如果SSIDcb被启用，则移动装置寻找蜂窝广播S879。在寻找蜂窝广播后，或者如果SSIDcb未被启用，则移动装置确定是否有RF指纹匹配S880。在该阶段，移动装置将它看见的现有小区站点与相关参数进行比较。如果任何两个小区站点处于其现有接入点列表的已存储指纹的例如6dB内，则移动装置接下来更新临时接入点列表S881，否则移动装置返回点8，此处将开始正常扫描及提示模式。若临时接入点列表被更新，则移动装置判断是否有要发送的数据S882。如果没有数据要发送，则移动装置前进到点8，此处将开始正常扫描及提示模式。如果有要发送的数据，则移动装置进入点10并激活Wi-Fi收发器S983，见图9。At this point, the mobile device proceeds to point 8, where the mobile device goes back to begin normal scanning and prompting mode. When the device is in the sleep mode S861, the mobile device remains in the sleep mode for a prescribed period of time, eg, 5 minutes. The mobile device then determines whether the time falls into the schedule S877. The user has predetermined the time periods during which the mode will work. This could be the day of the week, the start and end hours, etc. If the current time is within the allowed time period, the mobile device proceeds to the SSIDcb enable comparison stage S878. If the current time is not within the allowed time period, the mobile device proceeds to point 8, where the mobile device begins normal scanning and prompting mode. At SSIDcb enable compare stage S878, the mobile device determines whether it should seek cellular broadcast WiFi assistance. The help informs one or more access points in the area of the mobile device. If SSIDcb is enabled, the mobile device looks for cellular broadcast S879. After looking for the cellular broadcast, or if SSIDcb is not enabled, the mobile device determines if there is an RF fingerprint match S880. At this stage, the mobile compares the existing cell sites it sees with relevant parameters. If any two cell sites are within, say, 6dB of the stored fingerprints of their existing access point lists, the mobile next updates the temporary access point list S881, otherwise the mobile returns to point 8 where normal scanning and Prompt mode. If the temporary access point list is updated, the mobile device determines whether there is data to be sent S882. If there is no data to send, the mobile device proceeds to point 8 where normal scanning and prompting mode will begin. If there is data to send, the mobile enters point 10 and activates the Wi-Fi transceiver S983, see FIG. 9 .
在激活Wi-Fi收发器S983后，扫描寻找Wi-Fi接入点，任何找到的Wi-Fi接入点被收集并加入找到的列表中，检测到的接入点的列表与现有列表（用户、服务提供者定义的、或历史数据）进行比较，以确定是否有优选的接入点S984。如果发现一个或多个匹配，则移动装置根据信号强度、质量或其它度量（例如上述鉴定因子）对找到的接入点进行排名，并在点7将列表传递至公共连接及存储模式。如果未找到列表，则移动装置接下来判断是否找到其它接入点S985。如果找到了其它接入点，则移动装置接下来判断是否启用自动连接选项S965。如果未找到其它开放的接入点，则移动装置返回到点9处开始正常扫描及提示模式。如果自动连接选项被启用，则移动装置判断是否使用网络帮助S966。如果网络帮助选项不被启用，则移动装置接着按dBm对可用接入点的SSID进行排名。在该步骤，移动装置按dBm对开放SSID的列表进行排名，dBm是测得的功率相对于1毫瓦（mW）的功率比的分贝数的缩写。移动装置接着进入点7的公共连接及存储模式。如果网络帮助选项被启用，则移动装置将看见的接入点的列表发送到蜂窝网络上的服务器S971。这可以包括每个接入点的MAC地址。服务器对这些接入点进行排名，将结果发回移动装置并提示用户服务器所确定的顶部接入点。移动装置可以得到接入点的SSID、MAC地址、WiFiRSSI等。用户也能够看见可用接入点的完整列表。After activating the Wi-Fi Transceiver S983, scan for Wi-Fi access points, any found Wi-Fi access points are collected and added to the found list, the list of detected access points is the same as the existing list ( user, service provider defined, or historical data) to determine whether there is a preferred access point S984. If one or more matches are found, the mobile ranks the found access points according to signal strength, quality, or other metric (such as the authentication factor mentioned above) and passes the list to the public connection and storage mode at point 7 . If no listing is found, the mobile device next determines whether other access points are found S985. If other access points are found, the mobile device next determines whether to enable the automatic connection option S965. If no other open access points are found, the mobile device returns to point 9 to begin normal scanning and prompting mode. If the automatic connection option is enabled, the mobile device determines whether to use the web help S966. If the network assistance option is not enabled, the mobile device then ranks the SSIDs of the available access points in dBm. In this step, the mobile device ranks the list of open SSIDs by dBm, which is an abbreviation for the ratio of measured power to 1 milliwatt (mW) in decibels. The mobile device then enters the public connection and storage mode of point 7. If the network assistance option is enabled, the mobile device sends a list of access points it sees to a server on the cellular network S971. This can include the MAC address of each access point. The server ranks these access points, sends the results back to the mobile device and prompts the user for the top access points determined by the server. The mobile device can get the SSID, MAC address, WiFi RSSI, etc. of the access point. Users can also see a complete list of available access points.
此时，移动装置在点7进入公共连接及存储模式。如果自动连接选项未被启用，则移动装置判断移动装置最近是否曾到达该步骤S986。为了避免有人在同一位置时的重复连接，移动装置检查上一次它到达该阶段的时间。如果它最近的确曾到达该阶段，最近是指预设的时间量，移动装置返回到点9开始正常扫描及提示模式。如果移动装置最近未曾到达该阶段，则移动装置判断它是否能够连接到顶部接入点S987，顶部接入点即具有最高信号强度的接入点。如果移动装置不能连接到顶部接入点，则移动装置返回到点9开始正常扫描及提示模式。如果移动装置可以连接到顶部接入点，则移动装置运行诊断测试S988。该测试可以包括测量上载及下载的每秒平均字节，这是在10秒测试中测得的；测试ping延时；报告看见的小区ID等。在这阶段之后，移动装置返回到点9开始正常扫描及提示模式。At this point, the mobile device enters public connection and storage mode at point 7 . If the auto-connect option is not enabled, the mobile device determines whether the mobile device has reached this step S986 recently. To avoid repeated connections when someone is in the same location, the mobile device checks the last time it was in that phase. If it did reach that stage recently, last being a preset amount of time, the mobile device returns to point 9 to begin normal scanning and prompting mode. If the mobile device has not reached this stage recently, the mobile device determines whether it can connect to the top access point S987, ie the access point with the highest signal strength. If the mobile device cannot connect to the top access point, the mobile device returns to point 9 to begin normal scanning and prompting mode. If the mobile device can connect to the top access point, the mobile device runs a diagnostic test S988. The test may include measuring average bytes per second upload and download, measured in a 10 second test; testing ping latency; reporting cell IDs seen, etc. After this stage, the mobile device returns to point 9 to begin normal scanning and prompting mode.
图10根据本发明的一个示例性实施例示出了移动装置的公共连接及存储模式。在该实施例中，点2、5、7前进至连接到接入点S1089。移动装置试图根据接入点的优先级连接到接入点。提供者接入点可能是优选的，接着是公共或其它接入点的排序列表。移动装置接着判断是否已有连接成功S1090。如果连接没有成功，则移动装置返回到点6开始正常扫描及提示模式。如果连接成功，则移动装置运行诊断测试并将结果上载至蜂窝服务器S1091。该测试可包括：测量上载及下载的每秒平均字节，这是在例如10秒测试中测得的；测试ping延时；报告看见的小区ID等。在将该信息发送给服务器后，移动装置将连接的接入点存储到现有列表中S1092，并将该位置的RF指纹值与现有历史数据库值求平均。如果连接的接入点未存在于列表或数据库中，则当前接入点连同收集的其它值被加入列表中。在数据被上载后，移动装置接下来检查移动装置是否仍连接到该接入点S1093。如果移动装置已不连接，则移动装置返回到点6开始正常扫描及提示模式。如果移动装置仍在连接中，则移动装置判断是否有要发送的数据S1094，或者是否有高数据/高带宽应用是活动的。如果没有要发送的数据，移动装置判断计时器是否已超时S1096。如果计时器已超时，则移动装置返回到点6开始正常扫描及提示模式。如果计时器尚未超时，则移动装置返回判断它是否仍连接到接入点S1093。如果有数据要发送，则计时器被复位S1095，并且装置判断它是否仍连接到接入点S1093。FIG. 10 shows public connection and storage modes of a mobile device according to an exemplary embodiment of the present invention. In this example, points 2, 5, 7 proceed to connect to access point S1089. The mobile device attempts to connect to the access point according to the priority of the access point. Provider access points may be preferred, followed by an ordered list of public or other access points. The mobile device then determines whether the connection is successful S1090. If the connection is not successful, the mobile device returns to point 6 to begin normal scanning and prompting mode. If the connection is successful, the mobile device runs diagnostic tests and uploads the results to the cellular server S1091. The test may include: measuring average bytes per second upload and download, as measured in eg a 10 second test; testing ping latency; reporting cell IDs seen, etc. After sending this information to the server, the mobile device stores S1092 the connected access point in the existing list, and averages the RF fingerprint value for that location with the existing historical database value. If the connected access point does not exist in the list or database, the current access point is added to the list along with the other values collected. After the data is uploaded, the mobile device next checks whether the mobile device is still connected to the access point S1093. If the mobile device is not connected, the mobile device returns to point 6 to begin normal scanning and prompting mode. If the mobile device is still connected, the mobile device determines whether there is data to send S1094, or whether a high data/high bandwidth application is active. If there is no data to send, the mobile device determines whether the timer has expired S1096. If the timer has expired, the mobile device returns to point 6 to begin normal scanning and prompting mode. If the timer has not expired, the mobile device returns to determine whether it is still connected to the access point S1093. If there is data to send, the timer is reset S1095 and the device determines whether it is still connected to the access point S1093.
图11根据本发明的一个示例性实施例示出了在移动装置1101上的用户提示的快照。在该实施例中，当与服务提供者的优选WiFi网络之一间的连接不可用时，对用户进行提示。用户能够从移动装置已检测到的可用WiFi网络中进行选择。例如，在该例子中，与AT&TWiFi网络之间的连接不可用，用户被提示从包括Brad’sBaker和Joe’sJava在内的连接列表中进行选择。每个可用的WiFi连接都可以包括该连接的信号强度以及任何安全设置等。可以在检测到任何接入点时或者仅在检测到非授权接入点或公共接入点时在移动装置1101上呈现提示，或者可以基于用户或运营商定义的任何准则来列举。Figure 11 shows a snapshot of a user prompt on a mobile device 1101 according to an exemplary embodiment of the present invention. In this embodiment, the user is prompted when a connection to one of the service provider's preferred WiFi networks is unavailable. The user is able to select from available WiFi networks that the mobile device has detected. For example, in this example, a connection to the AT&T WiFi network is unavailable and the user is prompted to choose from a list of connections including Brad's Baker and Joe's Java. Each available WiFi connection can include that connection's signal strength as well as any security settings, among other things. The prompt can be presented on the mobile device 1101 when any access point is detected, or only when an unauthorized or public access point is detected, or can be enumerated based on any criteria defined by the user or operator.
图12根据本发明的一个示例性实施例示出了移动装置1201上用于更新网络的应用。在该实施例中，用户向蜂窝网络更新在移动装置的位置1299处可用的WiFi网络。例如，在用户的当前位置1299处，可用的连接是私有网络、Brad’sBaker和Joe’sJava。用户可以点击更新网络按钮，以便通知蜂窝网络在该位置处这些连接是可用的。该位置可由移动装置使用GPS、通过网络中的三角测量、使用RF指纹等来确定。用户还可以从列表中选择网络并对该网络的性能进行评级。这将测量接入点的属性，例如信号强度、带宽、可用性等。用户可以再次选择更新网络按钮，以将该信息发送给蜂窝网络。FIG. 12 shows an application for updating a network on a mobile device 1201 according to an exemplary embodiment of the present invention. In this embodiment, the user updates the cellular network with the WiFi networks available at the location 1299 of the mobile device. For example, at the user's current location 1299, the available connections are the private network, Brad's Baker, and Joe's Java. The user can click the update network button to notify the cellular network that these connections are available at this location. The location may be determined by the mobile device using GPS, by triangulation in a network, using RF fingerprinting, and the like. Users can also select a network from the list and rate the performance of that network. This measures attributes of the access point such as signal strength, bandwidth, availability, etc. The user can again select the update network button to send this information to the cellular network.
下面参考图13-17来描述几种WiFi接入点选择的示例性方法，包括指纹法以及网络和移动装置之间的命令。图13A-13B描述了确定流程的主模块。图14A-14B描述了对接入点排名、测试得到用户连接级、以及提示用户连接的连接模式。图15描述了当移动装置处于外部电源及空闲模式（即，当屏幕为空白时），并且处理器空闲，表示没有活动时被激活的超循环测试模式。图16描述了使用GPS或RF指纹来确定接入点（AP）是否位于移动装置附近的位置检查例程。图17A-17B描述了有能力捕获及修改RF指纹，并使用RF指纹连接及断开接入点的RF指纹测试应用。Several exemplary methods of WiFi access point selection, including fingerprinting and commands between the network and the mobile device, are described below with reference to FIGS. 13-17. 13A-13B describe the main modules of the determination process. Figures 14A-14B depict connection patterns for ranking access points, testing for user connection levels, and prompting users to connect. Figure 15 depicts a supercycle test mode that is activated when the mobile device is in external power and idle mode (ie, when the screen is blank), and the processor is idle, indicating no activity. Figure 16 describes a location check routine that uses GPS or RF fingerprints to determine if an access point (AP) is located in the vicinity of a mobile device. 17A-17B depict an RF fingerprint test application that has the ability to capture and modify RF fingerprints, and connect and disconnect access points using RF fingerprints.
参考图13A，该示例型的方法开始于移动装置的Wi-Fi收发器处于关闭状态S1300。步骤S1301判断NELOS方法S1302是否被调用来激活Wi-Fi收发器。如果是，则NELOS服务器传递的优选接入点（AP）被填入SSIDcom字段内，Wi-Fi收发器被打开或激活，计时器复位，方法前进到A，这是图14A-14B的流程的起点。然而，如果没有NELOS命令，则判断应用是否为首次运行S1304。如果是，则生成第一位置列表并添加到列表S1305。如果否，则假定列表已存在，激活睡眠模式S1307持续指定的期间。然后，确定S1308移动装置是否基本处于静止位置。这可以通过经由GPS等监视装置的移动来确定，如果速度低于阈值，则移动装置为静止。如果不是，则方法重新开始。Referring to FIG. 13A , the exemplary method begins with the mobile device's Wi-Fi transceiver in an off state S1300 . Step S1301 judges whether the NELOS method S1302 is called to activate the Wi-Fi transceiver. If yes, the preferred access point (AP) delivered by the NELOS server is filled in the SSIDcom field, the Wi-Fi transceiver is turned on or activated, the timer is reset, and the method proceeds to A, which is part of the flow of Figures 14A-14B starting point. However, if there is no NELOS command, it is judged whether the application is running for the first time S1304. If yes, generate a first location list and add to the list S1305. If not, assuming that the list already exists, the sleep mode is activated S1307 for a specified period. Then, determine S1308 whether the mobile device is substantially at a rest position. This can be determined by monitoring the movement of the device via GPS etc., if the speed is below a threshold then the mobile device is stationary. If not, the method starts over.
如果移动装置基本静止，则在S1309处判断是否提供了外部电源，例如墙上充电器或车载充电器等。如果是，步骤S1310确定为空闲模式（即，如果屏幕空白和/或如果处理器处于低功率状态），并且如果是，则方法使S1310继续至图15的超循环测试模式。如果没有外部电源并且在步骤S1312处确定装置处于空闲模式，则方法重新开始。如果装置没有处于空闲模式，则在步骤S1313测量RF环境的指纹，并与位置的列表进行比较（见图16）。如果存在匹配，则在步骤S1314处匹配的位置被加入列表。如果没有匹配，则该方法接下来在步骤S1315处判断是否想要填写或访问第二列表，例如群组列表（L2）。另一方面，如果该方法确定装置有外部电源但不处于空闲模式，则在步骤S1311处将位置填入列表中，在步骤S1315处判断是否有填写第二列表（L2）的选项。如果有，该方法前进至图13B的步骤S1320。如果没有，则在步骤S1316处判断位置列表是否全空。如果是，则激活超级睡眠部分S1317，从而计时器递增，与阈值n相比较，只要计时器低于n，则Wi-Fi收发器打开，确定可用AP的列表，并且方法前进至A，即图14A-14B的连接模式。如果计时器超时，则方法重新开始。If the mobile device is basically still, it is judged at S1309 whether an external power supply, such as a wall charger or a car charger, is provided. If yes, step S1310 determines idle mode (ie, if the screen is blank and/or if the processor is in a low power state), and if yes, the method continues S1310 to the hyperloop test mode of FIG. 15 . If there is no external power supply and it is determined at step S1312 that the device is in idle mode, the method starts over. If the device is not in idle mode, a fingerprint of the RF environment is measured at step S1313 and compared with the list of locations (see Figure 16). If there is a match, the matched position is added to the list at step S1314. If there is no match, the method next determines at step S1315 whether a second list, such as a group list (L2), is desired to be filled or accessed. On the other hand, if the method determines that the device has external power but is not in idle mode, the location is filled in the list at step S1311, and whether there is an option to fill the second list (L2) is determined at step S1315. If so, the method proceeds to step S1320 of FIG. 13B. If not, it is judged at step S1316 whether the location list is empty. If yes, the super sleep part S1317 is activated so that the timer is incremented and compared with the threshold n, as long as the timer is below n, the Wi-Fi transceiver is turned on, the list of available APs is determined, and the method proceeds to A, ie 14A-14B connection mode. If the timer expires, the method starts over.
同时，图13B描述了WiFi被打开状态下的方法，该方法开始于点2和3，这些点分别连接到图13A的步骤S1315和S1316。在步骤S1320，Wi-Fi收发器被打开，并使用要扫描的接入点的列表来对区域进行扫描。如果在S1322确定位置列表中有AP可用，则方法前进至A（图14）。类似地，在S1321，WiFi被激活并且方法前进至A。在步骤S1323，在没有L1中的接入点可用的情况下，可用的AP与群组列表L2相比较。可以借助来自其它移动装置的报告而生成群组列表，即，上述众包法（crowdsourcing）。如果与L2列表之间存在匹配，则方法前进至A。如果没发现匹配，则在S1324判断是否找到其它AP。如果根本没找到AP，则方法返回1，即，图13A的流程图的起点。如果找到了开放/可接入的AP，则S1325检查以确定L2列表是否可填充以新的AP，即，众包法。如果是，并且在S1326处3G网络可用，则在S1329处在列表L2中，AP的位置、日期等连同SSID和MAC地址一起被更新。如果L2不能被更新，则在步骤S1325或者由于在步骤S1326处缺少3G，在步骤S1327处按照接收的信号强度指示符（RSSI）对所有开放AP进行排名，并且这些开放AP被测试以确定是否AP提供了因特网连接。如果因特网访问不可用S1328，则方法返回到步骤1。如果因特网可用，则AP被用于执行S1329，并在步骤S1330处被断开。此时，来自网路上的应用服务器或其他服务器的响应被监视S1331。如果在S1332处与L2之间存在匹配，则方法前进到连接点A（图14）。如果没发现匹配，则调用第三列表L3选项S1333。如果第三列表不存在或者由于某种原因不可访问，那么方法返回到步骤1。如果第三列表存在，方法前进至与A连接。Meanwhile, FIG. 13B describes the method when WiFi is turned on, and the method starts from points 2 and 3, which are respectively connected to steps S1315 and S1316 in FIG. 13A . In step S1320, the Wi-Fi transceiver is turned on and scans the area using the list of access points to scan. If it is determined at S1322 that there are APs available in the location list, the method proceeds to A ( FIG. 14 ). Similarly, WiFi is activated and the method proceeds to A at S1321. In step S1323, in case no access point in L1 is available, the available APs are compared with the group list L2. The group list can be generated with the help of reports from other mobile devices, ie crowdsourcing as described above. The method proceeds to A if there is a match with the L2 list. If no match is found, it is judged in S1324 whether other APs are found. If no AP is found at all, the method returns 1, ie, the beginning of the flowchart of Figure 13A. If an open/accessible AP is found, S1325 checks to determine if the L2 list can be populated with new APs, ie crowdsourcing. If yes, and a 3G network is available at S1326, then at S1329 in list L2, the location, date, etc. of the AP are updated along with the SSID and MAC address. If L2 cannot be updated, at step S1325 or due to lack of 3G at step S1326, at step S1327 all open APs are ranked by Received Signal Strength Indicator (RSSI), and these open APs are tested to determine if AP Internet connection is provided. If Internet access is not available S1328, the method returns to step 1. If the Internet is available, the AP is used to perform S1329, and is disconnected at step S1330. At this point, responses from application servers or other servers on the network are monitored S1331. If there is a match with L2 at S1332, the method proceeds to connection point A (Fig. 14). If no match is found, the third list L3 option S1333 is invoked. If the third list does not exist or is not accessible for some reason, then the method returns to step 1. If a third list exists, the method proceeds to join with A.
图14A开始本发明的示例性方法的连接模式。S1435判断是否已收到NELOS唤醒命令。如果还没有，则来自列表L1、L2和L3的所确定的移动装置的AP评级被添加到默认扫描列表S1438，并且A列表被填充作为扫描列表。如果A列表和扫描列表仍最终为空、或者由于某种原因不可访问/被锁住，该方法回到步骤1。如果A列表在S1439为空但扫描列表不为空，则在S1441处执行测试，该测试包括对于最顶部的5个开放AP的因特网连接性的测试，测试成功的AP被加入列表，并且该方法回到图13A的步骤1。如果S1439显示A列表不为空，则S1442将AP压栈到A列表中，并基于列表的层级（L1、L2、L3）、RSSI组以及移动装置或服务器上的排名逻辑所确定的排名对这些AP进行排名。步骤S1443-1445确定列表L2和L3被启用，并判断顶部AP是否在这些列表之一中。如果AP在列表中但该列表未被启用，则该方法在1处重启。如果AP在列表中且列表已被启用，或者如果L2及L3AP都不在列表上，则方法前进至S1447，此处检测到数据活动的存在，即开放的3G连接。这可以包括例如利用阈值数据传输率来检测大量数据。如果未检测到3G活动，则在S1448处启动用户提示，从而如果提示被启用，则用户被提示切换到排名顶部的AP。如果被拒绝，则在S1437处从列表中移除该AP，并且方法回到A列表确定S1439。如果用户接受，或者如果提示S1448被禁用，则方法连接到APS1451。如果在S1452处确定提供了因特网访问，则该方法前进到该方法的指纹部分，使用连接点C链接到图14B的流程图。然而，如果没有因特网连接，则接入点的SSID被移除S1437并且继续A列表确定S1439。此外，如果在S1447处3G活动存在，则该方法前进至断开连接的用户提示，假如在S1449处确定允许的话。该提示供用户停止处理过程，否则它将自动继续进行。如果连接被断开S1450，则方法返回到图13A的第一步骤。如果否，则连接到APS1451。Figure 14A begins the connection mode of the exemplary method of the present invention. S1435 judges whether the NELOS wake-up command has been received. If not already, the determined mobile device's AP ratings from lists L1, L2 and L3 are added to the default scan list S1438, and the A list is populated as the scan list. If the A list and scan list still end up empty, or are inaccessible/locked for some reason, the method goes back to step 1. If the A list is empty but the scan list is not empty at S1439, the test is performed at S1441, the test includes a test for the Internet connectivity of the top 5 open APs, the successful APs are added to the list, and the method Go back to step 1 in Fig. 13A. If S1439 shows that the A list is not empty, then S1442 pushes the APs into the A list, and ranks them based on the list level (L1, L2, L3), RSSI group, and ranking logic determined on the mobile device or server. AP for ranking. Steps S1443-1445 determine that lists L2 and L3 are enabled, and determine whether the top AP is in one of these lists. If the AP is in the list but the list is not enabled, the method restarts at 1 . If the AP is on the list and the list is enabled, or if neither L2 nor L3 APs are on the list, the method proceeds to S1447 where the presence of data activity is detected, ie an open 3G connection. This may include, for example, utilizing a threshold data transfer rate to detect large amounts of data. If no 3G activity is detected, a user prompt is initiated at S1448 such that the user is prompted to switch to the top ranked AP if the prompt is enabled. If rejected, the AP is removed from the list at S1437, and the method returns to A-list determination S1439. If the user accepts, or if the prompt S1448 is disabled, the method connects to APS1451. If it is determined at S1452 that Internet access is provided, the method proceeds to the fingerprinting part of the method, using connection point C to link to the flowchart of Figure 14B. However, if there is no Internet connection, the SSID of the access point is removed S1437 and A-list determination continues S1439. Also, if 3G activity exists at S1447, the method proceeds to a user prompt to disconnect if it is determined to be allowed at S1449. This prompt is for the user to stop the processing, otherwise it will continue automatically. If the connection is disconnected S1450, the method returns to the first step of Fig. 13A. If not, connect to APS1451.
图14B显示了当移动装置最终连接到AP时执行的提供RF指纹的过程。从连接点C开始，步骤S1455开始指纹诊断过程并将结果上载到服务器。S1456在诊断结果与过去提交的先前RF指纹求平均后，将诊断结果保存在服务器上，并启动计时器（用timerC表示）。指纹被下载S1458并保存在电话上的L1列表中。如果连接断开或者超时，并且如果用户不处于静止（即，在移动）S1459，则方法在步骤1重新开始。如果连接终止或超时，并且如果用户处于静止，则附近的AP被扫描，并且连接过程在步骤A处重新开始。如果保持连接S1458，方法检测数据流S1462。如果没有数据流，则将计时器与阈值进行比较S1463，如果计时器在阈值内，则继续数据和计时器监视。如果有数据流，则数据流被监视，直至它停止。然而，如果没有数据流并且计时器达到阈值，则方法检查Wi-Fi收发器是否仍活动S1464。如果不活动，则方法在步骤1处重新开始。如果Wi-Fi收发器是活动的，但是没有外部电源S1465，则方法重新开始。如果有外部电源，但用户/移动装置处于运动中S1466，则方法重新开始。如果用户静止并且装置没有处于空闲状态S1467，则方法回到步骤S1458，启动连接、数据和计时器循环。然而，如果装置变为空闲，则方法经由连接点B连接到图15的超循环测试模式。Figure 14B shows the process of providing RF fingerprinting performed when the mobile device finally connects to the AP. Starting from connection point C, step S1455 starts the fingerprint diagnosis process and uploads the result to the server. S1456 After the diagnosis result is averaged with the previous RF fingerprints submitted in the past, save the diagnosis result on the server, and start a timer (indicated by timerC). The fingerprint is downloaded S1458 and saved in the L1 list on the phone. If the connection is disconnected or times out, and if the user is not stationary (ie moving) S1459, the method starts over at step 1 . If the connection is terminated or times out, and if the user is stationary, nearby APs are scanned and the connection process restarts at step A. If the connection is maintained S1458, the method detects data flow S1462. If there is no data flow, compare the timer with a threshold S1463, if the timer is within the threshold, continue data and timer monitoring. If there is data flow, the data flow is monitored until it stops. However, if there is no data flow and the timer reaches the threshold, the method checks if the Wi-Fi transceiver is still active S1464. If not active, the method restarts at step 1. If the Wi-Fi transceiver is active, but there is no external power S1465, the method starts over. If there is external power, but the user/mobile device is in motion S1466, the method starts over. If the user is stationary and the device is not in an idle state S1467, the method returns to step S1458 to start a connection, data and timer loop. However, if the device becomes idle, the method connects via connection point B to the supercycle test mode of FIG. 15 .
图15显示了AP列表的超循环测试模式。在S1568处，附近的AP被扫描。如果列表为空S1569，则方法返回到图13A的步骤1。然而，如果列表不为空，则用扫描列表的结果来填充A列表S1570。如果A列表返回空，则启动计时器，keep-alive计时器S1572被启动，从而如果移动装置保持非空闲（即，充分供电），接有外部电源，并且没有使用数据连接的其它应用，则计时器递增，直至它达到阈值n。一旦它达到阈值，则方法循环回到S1568，扫描AP。如果在S1571找到AP并且A列表被填充，则启动超循环测试循环，从而按RSSI对所有开放的AP进行排名，对因特网连接性进行测试，执行图14B的诊断部分（结果被保存或报告给服务器），然后断开。该方法循环往复，直至扫描列表变空，在这种情况下方法返回到第一步骤1。Figure 15 shows the hyperloop test pattern for the AP list. At S1568, nearby APs are scanned. If the list is empty S1569, the method returns to step 1 of Figure 13A. However, if the list is not empty, the A-list is populated S1570 with the results of scanning the list. If the A-list returns empty, a timer is started, a keep-alive timer S1572 is started, thereby timing if the mobile device remains non-idle (i.e., fully powered), has external power connected, and has no other applications using the data connection is incremented until it reaches the threshold n. Once it reaches the threshold, the method loops back to S1568 to scan for APs. If an AP is found at S1571 and the A-list is populated, a hyperloop test loop is started, ranking all open APs by RSSI, testing for Internet connectivity, performing the diagnostic portion of Figure 14B (results are saved or reported to the server ), and disconnect. The method iterates until the scan list becomes empty, in which case the method returns to the first step 1 .
图16根据本发明的一个示例性实施例示出了位置检查例程（见图13A的步骤S1313）。在该实施例中，移动装置和/或网络使用GPS或RF指纹来确定是否特定的接入点位于移动装置附近。该例程开始于启动位置检查S1673。判断移动装置的GPS是否打开S1674。这可以由移动装置完成并且报告给网络。如果GPS打开，则移动装置确定移动装置的当前位置的经度和纬度，移动装置和/或网络将这些坐标与例如L1接入点的位置进行匹配S1678。然后确定移动装置和L1接入点之间的距离是否小于预定距离S1679。如果距离小于预定距离，则存在匹配S1680并且该值被返回S1682。匹配是指可用的并且/或者在移动装置的当前位置的范围内的接入点。如果距离不小于预定距离，则没有匹配S1681，该非匹配值被返回S1682。如果GPS没有打开，移动装置获取服务中的小区、相邻小区以及接收的信号强度指示（RSSI）信息S1675。判断服务中的小区或相邻小区中是否有哪个与特定接入点的任何RF指纹相匹配S1676。如果有RF指纹匹配，则确定是否所有RSSI信息都在给定的阈值内S1677。如果RSSI信息在阈值内，则存在匹配S1680并且该值被返回S1682。如果没有RF指纹匹配或者所有RSSI信息都不在阈值内，则没有匹配S1681，并且该值被返回S1682。FIG. 16 shows a location check routine (see step S1313 of FIG. 13A ) according to an exemplary embodiment of the present invention. In this embodiment, the mobile device and/or the network use GPS or RF fingerprints to determine if a particular access point is located near the mobile device. The routine starts with a start position check S1673. Determine whether the GPS of the mobile device is turned on S1674. This can be done by the mobile device and reported to the network. If GPS is on, the mobile device determines the longitude and latitude of the mobile device's current location, and the mobile device and/or the network match these coordinates with, for example, the location of the L1 access point S1678. It is then determined whether the distance between the mobile device and the L1 access point is less than a predetermined distance S1679. If the distance is less than the predetermined distance, there is a match S1680 and the value is returned S1682. A match refers to an access point that is available and/or within range of the mobile device's current location. If the distance is not less than the predetermined distance, there is no match S1681, and the non-match value is returned to S1682. If GPS is not turned on, the mobile device obtains serving cells, neighboring cells and received signal strength indication (RSSI) information S1675. Determine whether any of the serving cell or neighboring cells match any RF fingerprint of the particular access point S1676. If there is an RF fingerprint match, it is determined whether all RSSI information is within a given threshold S1677. If the RSSI information is within the threshold, there is a match S1680 and the value is returned S1682. If there is no RF fingerprint match or all RSSI information is not within the threshold, then there is no match S1681 and the value is returned S1682.
图17A和17B描述了有能力捕获及修改RF指纹、以及使用RF指纹连接及断开接入点的RF指纹测试应用。如图17A所示，该方法开始于S1783，判断移动装置是否连接到接入点S1784。如果移动装置连接着，则判断是否存在SSID的RF指纹S1785。如果存在RF指纹，则应用能够修改该SSID的RF指纹S1788。该修改可包括修改CellID、PSC、RSSI范围等。然后对于该SSID设置RF指纹ID。如果不存在SSID的RF指纹，则移动装置手动捕获或输入该SSID的RF指纹S1786。一个RF指纹样本如下所示：Figures 17A and 17B describe an RF fingerprint test application with the ability to capture and modify RF fingerprints, and to connect and disconnect access points using RF fingerprints. As shown in FIG. 17A, the method starts at S1783, and determines whether the mobile device is connected to the access point S1784. If the mobile device is connected, it is determined whether there is an RF fingerprint of the SSID S1785. If there is an RF fingerprint, the application can modify the RF fingerprint of that SSID S1788. This modification may include modifying the CellID, PSC, RSSI range, and the like. The RF Fingerprint ID is then set for that SSID. If there is no RF fingerprint for the SSID, the mobile device manually captures or enters the RF fingerprint for the SSID S1786. A sample RF fingerprint looks like this:
SSID的RF指纹=LinksysRF Fingerprint of SSID = Linksys
PSC1=105,RSSI1=-75PSC1=105, RSSI1=-75
PSC2=106,RSSI2=-80PSC2=106, RSSI2=-80
PSC3=-100,RSSI3=-90。PSC3=-100, RSSI3=-90.
移动装置捕获例如发现的指纹、SSID、小区ID、PSC、RSSI的范围，并记录该信息S1787。然后对于SSID设置RF指纹IDS1789。如果移动装置没有连接到接入点，则移动装置打开Wi-Fi收发器并扫描寻找接入点S1788。然后确定是否找到了接入点S1791。如果没找到接入点，则在计时器设置的一段时间内关闭Wi-Fi收发器，例如1分钟S1792，方法在S1783处再次开始。如果找到了接入点，则判断是否有RF指纹匹配S1790。如果有RF指纹匹配，则对于该接入点设置RF指纹IDS1789。如果没有RF指纹匹配，则移动装置连接到期望的SSIDS1793并且方法再次开始S1783。在为接入点设置了RF指纹ID后，方法前进到连接点D，其通往图17B。The mobile device captures eg discovered range of fingerprints, SSID, cell ID, PSC, RSSI and records this information S1787. Then set RF Fingerprint IDS1789 for SSID. If the mobile device is not connected to an access point, the mobile device turns on the Wi-Fi transceiver and scans for an access point S1788. Then it is determined whether the access point is found S1791. If no access point is found, the Wi-Fi transceiver is turned off within a period of time set by the timer, for example 1 minute S1792, and the method starts again at S1783. If the access point is found, judge whether there is an RF fingerprint matching S1790. If there is a RF fingerprint match, set the RF fingerprint IDS1789 for that access point. If there is no RF fingerprint match, the mobile device connects to the desired SSIDS 1793 and the method starts again S1783. After the RF Fingerprint ID is set for the access point, the method proceeds to connection point D, which leads to Figure 17B.
参考图17B，睡眠计时器S1794被设置一个时间段，例如1分钟。在该睡眠时间段后，S1795通过参考相邻列表来搜寻服务中的小区及相关的PSC。落入范围内的值的例子是：Referring to FIG. 17B, the sleep timer S1794 is set for a period of time, for example, 1 minute. After the sleep period, S1795 searches for serving cells and related PSCs by referring to the neighbor list. Examples of values that fall within the range are:
PSC1=105,RSSI1=-80PSC1=105, RSSI1=-80
PSC2=106,RSSI2=-78PSC2=106, RSSI2=-78
PSC3=56,RSSI3=-50。PSC3=56, RSSI3=-50.
未落入范围内的值的例子是：Examples of values that do not fall within the range are:
PSC1=105,RSSI1=-80PSC1=105, RSSI1=-80
PSC2=106,RSSI2=-90PSC2=106, RSSI2=-90
PSC3=56,RSSI3=-50。PSC3=56, RSSI3=-50.
如果小区和PSC值被检测在AP的RSSI范围内，则连接被检查S1797。Wi-Fi收发器被激活并连接到特定AP。如果检测到的值不在RSSI范围内，则监视Wi-Fi收发器S1799，如果必要则关闭Wi-Fi收发器。在两种情况下，利用报告形式的结果，即“断开”或“连接”，来填写日志文件。If the cell and PSC values are detected to be within the RSSI range of the AP, the connection is checked S1797. The Wi-Fi transceiver is activated and connected to a specific AP. If the detected value is not within the RSSI range, monitor the Wi-Fi Transceiver S1799 and turn off the Wi-Fi Transceiver if necessary. In both cases, the log file is populated with the result in the form of a report, ie "disconnected" or "connected".

In this embodiment, the opportunity list 2480 may be populated with access points that have been seen during the scan, but not used or saved. A user may select box 2481 to add or drop an access point. This enables the user to add access points to the "My Points" list as desired, or to deprecate certain access points so that the availability of deprecated access points does not generate a reminder to the user. The opportunity list 2480 may include the number of times the access point has been seen during the scan, the security of the access point, the date and time the access point was seen, a rating, and the like. After the user has made a selection, the user may press "Done" 2482 to execute the selection.
根据本发明的多个实施例，更新蜂窝网络也可以向网络发送关于移动装置的当前位置的RF指纹，该位置通过GPS等来确定。蜂窝网络可以用该新信息来更新应用服务器上的数据库，以做出更精确的位置的进一步确定，特别是对缺少GPS能力的装置。此外，动态智能可以考虑订户密度或者每蜂窝扇区的订户数量，并使用该信息来平衡蜂窝塔和Wi-Fi或相当的接入点之间的负载。带有特定装置（例如PDA或iPAD等）的高吞吐率的顾客或用户可以转移到无线局域网，而常规的语音和文本用户可以继续留在蜂窝网络中。每类装置的唯一简档可被存储在网络上，由逻辑基于装置类型来确定如何负载平衡网络访问。该逻辑可以位于网络上的服务器中、移动装置自身中、以及它们的任何组合中。根据本公开的内容，其它组合方式是可能的，并且对于本领域技术人员是清楚的。According to various embodiments of the invention, updating the cellular network may also send an RF fingerprint to the network regarding the mobile device's current location, as determined by GPS or the like. The cellular network can update a database on the application server with this new information to make further determinations of more precise location, especially for devices lacking GPS capabilities. Additionally, dynamic intelligence can take into account subscriber density, or the number of subscribers per cell sector, and use that information to balance load between cell towers and Wi-Fi or equivalent access points. High-throughput customers or users with specific devices (such as PDAs or iPADs, etc.) can migrate to the wireless LAN, while regular voice and text users can remain on the cellular network. A unique profile for each type of device can be stored on the network, with logic determining how to load balance network access based on the type of device. This logic can be located in a server on the network, in the mobile device itself, and any combination thereof. Other combinations are possible and will be clear to those skilled in the art in light of this disclosure.
